"If you disapprove of affirmative action, forget pursuing a degree in African-American studies. If you think that the nuclear family proves the best unit of social well-being, stay away from women's studies."
Few have made note of the fact, that the sheer numbers of far-lefties on campus is greatly enhanced by the existance of these new "disciplines". And sadly, industry seems to encourage people who pursue degrees in these areas by offering them extremely high-paying positions in order to appear as properly PC.
The "chairs" of these "colleges" are often funded through endowments. Think of the usual suspects supporting NPR, and you get some idea who is funding this BS. Thomas Sowell & Walter E. Williams have been very critical of the intellectual rigor found in these academic disciplines (and I use that term advisedly).
The embedding of political philosophy into a particular course of study is a very big problem. After all, who cares if your mathematics professor is a liberal? But try getting through a social science class with a liberal professor -- it's like negotiating a minefield.
